I think it is rather reprehensible when manufacturers: A. Make representations about what their equipment will do that are dramatically different from normal experience or.. B. Market something as a piece of production equipment that will not last long under continuous use. When I build something, I build it for ME first. Then, if it works well I will see about marketing it. Got a number under development, but not set up for production yet. Keith

Thank you very much. If you have any specific questions, you can also just ask. keith

You're welcome. Unfortunately I have no direct experience with ball or SAG mills, or floatation. I would love to learn more sometime, but those darn bills kinda hinder going back to school. Grrrr... They are usually not the most apropos for micro scale mining anyway though-so for now it's jaw before impact with possibly a rolls thrown in the middle. Thank you for the kind words. It makes it worthwhile. Keith

Thank you

Excellent! Combined with the hand panning you are practically set up to run a gravity ore. For a non-toxic leach you are in good shape also, but ore grade determination would be more difficult.

@@hardrockuniversity7283 Yes ive been sieving to 25 mesh which is 710 micron but my big bits of gold are only 150 micron, (ive measured then under a microscope with a micron marked slide) maybe 200 but with also fine and ultra fine gold. So I think Im going to have to sieve with 100 mesh so my quartz ore and gold bits are the same size so I can gravity sort on my M7 Wave table

@@peterheylen8640 It's worth a try, but a standard wave table seems to be slow because too much feed packs the beds. Make sure you keep good fluidization.

@@hardrockuniversity7283 You are 100% correct. The packing under the first riffle bar and keeping it fluid are the issues. Ive been thinking about other options

@@peterheylen8640 I have been working on some options......

+jdeluisa I'm trying. Have some more days off so I am working on the next video. Hopefully it should be up soon. The programmer also expects the new web site to be up next week. May be able to go for a prospecting trip the weekend of 2-13 and 14. Keith

You are most welcome.

What do you need to know?

You're welcome.

Sure. We would have to set up a time, but that shouldn't be too hard. Why don't you email me at HardRockU@outlook.com?

@@hardrockuniversity7283 awesome will do

Nothing wrong with nerdity. It has become quite popular in some circles.

I have seen an 'ultrasonic' ball mill once. Seemed to work OK. I've just built a prototype of an impact mill that seems to do well. It is air classifying, so the output is much more consistent than a standard impact mill.

@@hardrockuniversity7283 I definitely see merits in air classification as well, especially when it comes to fines which would want to float on top of water and be carried away, I also figure one can build an inertial staircase inside of a ball mill specifically for lifting the heavies from the bottom and depositing them separately from the bulk of the grind, it just has to be such a stair case that blocks out larger, lighter particles. Between those 2 [air and inertia] one should be able to readily and rapidly sort their heavies at all mesh sizes. Then, of course, comes in the question of efficient air moving equipment for high volume, but with precision air flow control so that neither too much air or too little air is delivered to the sorting areas. I have a small roots type blower [ 2" inlet and outlet] (can be mounted to gas or electric, or even water wheel input) and a gas operated leaf blower as well as some old vacuum cleaner motors, so I can work with either an electrically or engine driven air supply. With the large volume of water the land is offering, I do hope to be able to employ a water wheel to do a lot of my work because it would be cheaper in the long run than fuel or electricity, assuming I can make a cost effective flume down the valley. My thoughts on the flume is to cut it as much as possible from the hillside as a contouring canal, and then use chert stone and concrete for the balance of the outer walls where trenching can not be economically performed. It may prove financially unrealistic I admit. Will just have to play that one by ear.

@@hardrockuniversity7283 I come from a family of engineers, machinists, and other nerdlike professions, so it would be a stain on my family's good nerdy name to do things in some rudimentary way. [HOP HOP HOP!]

@@DeliciousDeBlair I wouldn't call engineering and machining 'nerdlike' personally. One can actually get icky hands and might even BLEED!
